In this paper we demonstrated Design and implementation of new aerospace elements which requires the use
of 3D-CAD modeling techniques and rapid prototyping, which makes it possible to significantly accelerate the deployment of
new solutions. In this paper we demonstrate, one of the rapid prototyping techniques FDM is used to produce the working
model of Aircraft Wheel hub. Meanwhile the task is to reduce the stress concentration in the Wheel Hub due to body weight
of aircraft and other loads on the wheel hub. For design of the wheel hub Catia V5 is used. It is analysed by using the
ANSYS. While analyzing the stress, stress concentration is found in the fixed regions (location of its bolts). The stress
concentration is checked in three ways and selecting the one which gives the optimum stress concentration. The three ways
are Design modification, Material changing without design modifications, material changing with design modification. From
these three ways we will find out optimum changes in stress concentration. After selecting the best design and converting
that 3D-CAD file into STL file or saving file in STL form. That STL file is used for direct developing of prototyping model by
using FDM process.

All the authors, conference coordinators, conveners, and guest editors kindly check their articles' originality before submitting them to IJCERT. If any material is found to be duplicate submission or sent to other journals when the content is in the process with IJCERT, fabricated data, cut and paste (plagiarized), at any stage of processing of material, IJCERT is bound to take the following actions.
1. Rejection of the article.
2. The author will be blocked for future communication with IJCERT if duplicate articles are submitted.
3. A letter regarding this will be posted to the Principal/Director of the Institution where the study was conducted.
4. A List of blacklisted authors will be shared among the Chief Editors of other prestigious Journals
We have been screening articles for plagiarism with a world-renowned tool: Turnitin However, it is only rejected if found plagiarized. This more stern action is being taken because of the illegal behavior of a handful of authors who have been involved in ethical misconduct. The Screening and making a decision on such articles costs colossal time and resources for the journal. It directly delays the process of genuine materials.
